Still making great progress on sms/kbd/ps2ctl. Still matching ref
binary.

Getting good! still advancing on ps2ctl in sms/kbd and still
matching reference binary.

cdddfdefae avra: add a layer of indirection to FLBL! 
This will make it easier to fit BR* in there.

0f2d14ad8a z80a: add BREAK, instruction 
This allows us to remove a lot of labels usage in boot code. This
commit has no effect on forth.bin.

bd38d80f9c Move Cross-compiled core from B390 to B350 
and renamed it "Core words". Also, reworded the presentation.

ca60685067 Streamline initialization process 
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

0163af470a Fix EOT behavior after QUIT 
Previously, calling quit would break EOT behavior and not properly
quit Collapse OS.

87b51a6261 By default, allocate about 0x100 bytes for PSP+RSP 
During "make updatebootstrap", we use less than 0x20 bytes on the
PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought
to be enough for anybody.

bf289b0a67 z80a: de-variable-ize 
Use straight VARIABLE instead of Z80MEM+. Initially, I used this
system to allow z80a to be embedded in a system binary, but now
I don't think it's worth it. Compiled, z80a is 2.5k. Sure, it's a
sizeable amount of RAM, but I think that even with it in RAM, I'll
manage a bootstrap within my most constrained machine, the SMS with
8K.

Not worth the trouble. Easier to set jump in binary directly.

e6bac985fa Cross-compiles in a single stage! 
Finally got rid of the XPACKed core and managed to cross-compile
all core words, which greatly simplifies the bootstrapping process.
